We are talking about a room sized enclosure, letís call it a room. In order to clean it you have to walk into the enclosure / room, so donít reduce the height to 150 cm / 5 ft, use the full height of the room you build it in so you can stand in it.

But if I have a 150cm tall enclosure, then I can stack two on top of each other having a cage for two burmese pythons in the same floor space one requires. Basically because a female is larger, have the bottom cage be for the female, then the above cage for the male.
